Woo Audio Tube Mini Dongle As a tube fan, about a year or so ago I bought this wonderful Woo Audio ‘Tube Mini’ tubed dongle-DAC. Believe me, it sounds fantastic, and has an amazing output capacity given it works of your source device’s battery. Having said that, I found I am sadly not a dongle-DAC / linked earphones person. In the end (no matter how GOOD this sounds) I find I reach for the phone, and my Focal Bathys LDAC bluetooth headphones. So better this little gen goes to someone who will use it and love it. As a result, this has had maybe only 10 or 12 hours use, and is essential

Woo Audio is a New York-based high-end audio company founded in the mid-2000s, with 2006 widely cited as its launch year. It was built by the Wu family, with Jack Wu as the public face of the brand and key design influence, alongside family members who helped shape the company’s early growth. Its roots are in tube electronics and a strong appreciation for live sound, which has remained central to its identity.
The brand is best known for vacuum-tube headphone amplifiers, especially models such as the WA series, along with electrostatic headphone amplifiers like the WES. Woo also makes a smaller range of speaker amps, plus related audio accessories and cables, while its website and retail focus remain centered on amplification and headphone-oriented listening rather than source components or turntables.
In the market, Woo Audio sits firmly in the boutique high-end niche. It is respected among headphone enthusiasts for handcrafted, valve-based designs, substantial build quality, and a distinctive sonic character often associated with warmth, scale, and refinement. It is not a mass-market brand; instead, it appeals to serious buyers looking for premium, specialized amplification with a strong American-made identity.
